 Eu. B. M. 2361, 5806. B.R. 801. L.B.C. 20:1970.—

 lanceolate, the outer herbaceous; the inner partly

 J.H. III. 54:437 (var. delicala). R.B. 30:145 (variety 

 with variegated lvs.). — The spathe-valves entirely 

 scarious even in the bud, the more comphcated infl. 

 and the fragrant fls. distinguish this species from 

 /. germanica. Var. daknatica, Hort. Lvs. 2 in. wide, 

 broader than those of the type, very glaucous: st. 

 shorter and stouter than that of the type: fls. lilac-pur-
